ITED STATES PATENT OFFICE.

PERRY S. BAUER, OF CHICAGO, ILLINOIS, ASSIGNOR TO BAUER & BLACK, OFCHICAGO, ILLINOIS, A CORPORATION OF ILLINOIS.

ADHESIVE-PLASTER SPOOL.

To all whom, it may concern:

Be it known that I, PERRY S. BAUER, a

citizen of the United States, residing at Chicago, in the county of Cookand State of Illinois, have invented certain new and useful Improvementsin Adhesive-Plaster Spools, of which the following is a specification.

My present invention relates to spools for plaster bandages and the likeand has for its object broadly to provide new and improved means forcutting off portions of the bandage or other material wound ,upon thespool.

A further object of the invention is to construct a plaster spool ordevice of like character provided with means for cutting off desiredportions of the material wound thereon which will consist of a minimumnumber of simple and cheaply constructed arts.

,Additional objects and advantages of the invention will be apparentfrom the following description taken in connection with the accompanyingdrawing illustrating two preferred embodiments thereof.

On the drawing: Figure 1 is a sectional view taken between and parallelto the side I walls of a spool embodying my invention; Fig. 2 is asectional view taken on the diameter of the side wall; and Figs. 3 and 4are partial sectional views taken similarly to Figs. 1 and 2, showing asomewhat different arrangement of the cutters.

Referring to the drawing, the plaster spool embodying my invention iscomposed of a pair of side walls 5 connected in any suitable manner witha spindle or barrel 6 upon which the plaster or other material 7 iswound. Each of the side walls 5 is providcd with acutting edge 8extending about its periphery. In the present instance this cutting edgeconsists of a plurality of sharp serrations or saw-teeth formed in theedge of the side wall, although it will be apparent that the edge of theside wall may be merely sharpened without departing from the spirit andscope of my invention.

In the embodiment of the invention shown in Figs. 1 and 2 the edge ofeach side wall is bent to provide a shoulder or rounded portion 9 whichterminates in the serrations 8,

which rounded portion serves to strengthen the wall adjacent the cuttingedge and permits the cutting edge to be inclined toward the other walland yet remain substantially in the plane of the wall upon which it isformed.

In the embodiment of the invention shown in'Figs. 3 and 4 the serrations11 are disposed radially of their end wall and those of one wall aresubstantially parallel to those of the other. In this embodiment thebent portions 12, similar to the bent portions 9, are provided adjacentand inwardly of these cutting edges and serve merely to stiffen thewalls.

When it is desired to cut off a portion of the material wound upon thespool this portion is merely unwound and laid over against one of thecutting edges formed about the periphery of the Walls and heldthereagainst by the operator while the end extending beyond the edge ispulled to cut the material. It will be apparent that no additionalmembers are required to provide the spool herein described with meansfor cutting the material wound thereon and that a finished spool made inpursuance of my invention may be cheaply constructed and will beeffcient in operation.

It is thought that the invention and many of its attendant advantageswill be understood from the foregoing without further description and itwill be obvious that vari ous changes may be made in the form andconstruction of the side walls of the spool, as for instance it may befound desirable to only provide one side wall with a cutting edge,without departing from the spirit or scope of the invention orsacrificing any of its material advantages, the forms hereinbeforedisclosed being merely preferred embodiments thereof.

I claim:

An adhesive plaster package comprising a spool having circular endsprovided with serrated cutting edges, and a plaster bandage wound onsaid spooll PERRY S. BAUER.
